Nanoparticle size and electronic conduction characteristics in fullerenes

Note: The important feature of all nanostructures is that the number of surface atoms in them is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature.

The range of nanoparticle activity change depends on the nature and shape of the nanostructure. With However, if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if in a certain range wavelength with the occurrence of chemical reactions in materials Under irradiation, the activity of nano particles up to 100 nm will be significant. In general, the results of nanoparticle energy growth can be expressed as the total energy of atoms on the surface of the particle. The freedom of movement of atoms on the surface of nanostructures is limited and only vibrational movements and the movement of electrons are possible. These two electrokinetic reactions are dependent on each other because the displacement of electron clouds of atoms definitely changes the vibrational frequencies of the bonds of nanoparticle atoms. On the other hand, changing the location of valence electrons in the bonds changes the polarity of the bond and objects known as supermolecule . In this case, electron transfer to a higher energy level becomes possible. In this sense, CNTs carbon nanotubes are the most interesting species to be investigated. Carbon nanotubes that protect them from the environment interact in these nanotubes, and for this reason these CNTs nanotubes are called metal nanotubes. / is called carbon.

Fullerenes are identified according to the number of atoms in their structure. A letter C is used to name fullerenes, which represents the carbon atom in their structure. After the letter C, the number of carbon atoms in the fullerene spherical lattice unit is mentioned. For example, C60 molecule has 60 carbon atoms. The number of atoms in fullerenes produced so far ranges from 28 to hundreds of carbon atoms.

Conclusion:

The important feature of all nanostructures is that the number of surface atoms in them is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature.
